Transit Mixer Eaton 4623 5423 6423 7620 pump

Hydraulic Eaton concrete mixer truck pump 4623 5423 6423 7620

Description

Closed circuit

Nominal Pressure: 420 bar (6000 psi) and Peak Pressure 480 bar (7000 psi)

Displacement from 63.7 to 124,8 cm3/r (3,89 to 7,62 in3/r)

Eaton has the lead position in providing reliable and durable system solutions for transit mixers—vehicles on which downtime can mean disaster. Whether the truck is traveling down a highway or idling at a traffic light, the drum must maintain a consistent rotation speed. That’s no problem when Eaton is on the inside. Eaton pump and motor provide the high pressure and high flow required to keep drums rotating.

Drive shafts – a wide variety of options are available to suit every need.

High strength swash plates on variable pumps and motors – resist deflection under high load.

High strength cast iron housings – provide greater noise damping and wall strength.

High flow check valves in pumps – keep the system primed with minimal pressure drop.

Charge pumps on pumps – gerotor type, several displacement options are available to suit the needs of every application. All cast iron construction.

Cartridge shaft seal – lends itself to easy serviceability. Mechanical face seal design tolerates high speed and high case pressures.

Technical Data 

Table of values (theoretical values, without efficiency and tolerances; values rounded)

Pump performance calculated at 96% efficiency.

*The maximum pump shaft speed may be limited by the charge pump speed rating.

** Nominal Pressure: Max delta system pressure at which component fatigue does not occur (pump life estimated by bearing life).

*** Peak Pressure: Max operation pressure which is permissible for a short duration of time (t < 1 sec).
